  high 
  on 
  the 
  body-whorl. 
  The 
  labrum 
  is 
  strongly 
  lobed 
  above 
  

   the 
  middle 
  and 
  bayed 
  immediately 
  below; 
  on 
  the 
  lower 
  part 
  

   of 
  this 
  lobe 
  the 
  peristome 
  is 
  slightly 
  thickened, 
  almost 
  to 
  the 
  

   extent 
  of 
  forming 
  an 
  eleventh 
  plait, 
  between 
  which 
  and 
  the 
  

   foliated 
  extension 
  of 
  the 
  lower 
  parietal 
  plait 
  is 
  formed 
  a 
  

   partly 
  covered 
  channel 
  to 
  the 
  interior.

  A.-; 
  a 
  contribution 
  towards 
  the 
  elucidation 
  of 
  this 
  intricate 
  

   group, 
  Mr. 
  J. 
  It. 
  le 
  B. 
  Tomlin 
  has 
  kindly 
  sent 
  me 
  a 
  .shell, 
  

   received 
  by 
  him 
  many 
  years 
  ago 
  from 
  either 
  Mr. 
  Ancey 
  or 
  

   Miss 
  Glanville 
  as 
  representing 
  Ancey's 
  species. 
  It 
  is 
  not 
  

   likely 
  to 
  be 
  a 
  co-type, 
  as 
  Ancey 
  only 
  mentio 
  one 
  

  

  locality, 
  East 
  London, 
  and 
  Mr. 
  Tomlin's 
  shell 
  comes 
  from 
  

   Albany 
  : 
  moreover, 
  it 
  does 
  not 
  agree 
  in 
  detail 
  with 
  Ancey's 
  

   description 
  ; 
  1 
  can 
  therefore 
  only 
  consider 
  it 
  a 
  second 
  variety. 
  

   I 
  am 
  indebted 
  to 
  Mr. 
  W. 
  L. 
  Radford 
  1<jv 
  a 
  further 
  example, 
  

   agreeing 
  in 
  all 
  essentials 
  with 
  Mr. 
  Tomlin's 
  shell, 
  which 
  he 
  

   collected 
  for 
  me 
  at 
  East 
  London. 
  As, 
  therefore, 
  my 
  only 
  

   two 
  specimens 
  come 
  from 
  different 
  localities, 
  a 
  geographical, 
  

   varietal 
  name 
  seems 
  inexpedient; 
  I 
  therefore 
  propose 
  to 
  

   iate 
  it 
  with 
  Mr. 
  Tomlin's 
  name 
  : 
  — 
  

  

  Var. 
  tomlinif 
  new 
  var. 
  (PI. 
  X. 
  fig. 
  1.) 
  

  

  Shell 
  like 
  var. 
  darglensis, 
  but 
  larger 
  and 
  more 
  conical, 
  with 
  

   peristome 
  less 
  effusively 
  expanded, 
  callus 
  not 
  extending 
  so 
  

   high 
  on 
  the 
  body-whorl, 
  and 
  aperture 
  not 
  so 
  much 
  closed 
  by 
  

   plaits. 
  The 
  lobe 
  and 
  sinus 
  of 
  the 
  labrum 
  are 
  less 
  developed 
  

  

  and 
  the 
  thickening 
  of 
  the 
  peristome 
  on 
  the 
  lower 
  part 
  of 
  the 
  

   lobe 
  " 
  almost 
  forming 
  an 
  eleventh 
  plait" 
  is 
  entirely 
  absent, 
  

   its 
  place 
  being 
  taken 
  by 
  the 
  first 
  labial 
  plait. 
  The 
  lo 
  

   parietal 
  plait 
  is 
  shorter 
  and 
  its 
  foliated 
  extension 
  to 
  the 
  peri- 
  

   stome 
  much 
  less 
  effuse, 
  leaving 
  the 
  sutural 
  canal 
  more 
  open. 
  

   In 
  place 
  of 
  the 
  two 
  inrnnning 
  plaits 
  on 
  the 
  base 
  of 
  the 
  peri- 
  

   stome 
  there 
  is 
  only 
  one, 
  about 
  equidistant 
  between 
  the 
  lo 
  

   labral 
  and 
  lowest 
  columellar 
  plait. 
  Tin; 
  colour 
  of 
  the 
  

   varietal 
  type 
  is 
  almost 
  white, 
  that 
  of 
  the 
  co-type 
  pale 
  brown.

  In
